Answer:
Alveoli.
Explanation:
Respiration may be defined as the process of exchange of gases between the environment, lungs and body tissues. Energy is given off during the process of respiration.
The alveoli is a ballon like structure present in the lungs when gases are inflated in the alveoli. The alveoli increses the surface area for the exchange of gases. Oxygen is transferred in the body tissue from the alveoli.
Thus, alveoli is the main site of gas exchange in the lungs.
Answer: The thalamus is located in the center of the underneath part of the brain and is directly above the brain stem. It's main function is to relay motor and sensory signals to the cerebral cortex. The hypothalamus is located directly under the thalamus and it's main function is linking the endocrine system to the nervous system via the pituitary gland. The limbic system is located on both sides of the thalamus and it's main function is to regulate autonomic or endocrine function in response to emotional stimuli and also is involved in reinforcing behavior.

The OMB has said that agencies should not include excessive information about their IT systems. Some agencies may have IG who reviews the information about the controls and carryout his evaluations to make controls better.
Since sample a has data more tightly clustered about the mean compared to sample b, we can say that the variance for sample a is lower than that for sample b.
What is variance:
Variability gets used to measure the central tendency's closeness to the values. A measure of central tendency that can get used is mean. Mean refers to the average for some given values and gets determined by dividing the sum of those values by the number of values. The variance refers to the average squared difference of each value from the mean.
When the variance is lower, the data is less spread out. Thus, data being more tightly clustered about the mean reflects lower variance. Since sample a has data more tightly clustered about the mean compared to sample b, it can be concluded that the variance for sample a is lower than that for sample b.
